硬球玻璃成形器中的几何阻挫和静态相关

Geometrical Frustration and Static Correlations in Hard-Sphere Glass Formers

Benoit Charbonneau, Patrick Charbonneau, Gilles Tarjus

摘要:

我们分析和数值表征硬球流体的结构,以审查各种几何挫折的玻璃化转变的情况。我们发现广义多面体的顺序与流体填充分数的增加,但变得越来越无关,随着尺寸的增加。我们还发现,结构相关性的增长是适度的,在计算机模拟访问的动态制度。

英文摘要:

We analytically and numerically characterize the structure of hard-sphere fluids in order to review various geometrical frustration scenarios of the glass transition. We find generalized polytetrahedral order to be correlated with increasing fluid packing fraction, but to become increasingly irrelevant with increasing dimension. We also find the growth in structural correlations to be modest in the dynamical regime accessible to computer simulations.
